[Radiusplugin-users] FreeBSD and openvpn

[Alexander Logvinov]

Hello!

 I got a openvpn freeze during client connection with radiusplugin from CVS:

FreeBSD 8.0-RELEASE i386
OpenVPN 2.1.r20

$ ldd ./radiusplugin.so

 And that is all. :( openvpn process is freezing after that. What is
wrong? Thanks!
